Trim fixing
 

Just to be certain, is the correct way to fix trim to push fat end into fixing hole, tap narrow pin through to lock clip and then slide trim over clips or is there a different way?

white clips
 

Hi George, you push the white clips into the holes in the body. Then you gently hammer or push the circular center in, locking the clip. Then you click the trim strip over the white clips. Don't try to slide them.

The trim doesn't go onto the clip square. If you hammer it on it'll damage the trim stripe. You hook one side in, (I prefer to push upwards so hook in the bottom edge). The top then can be forced over the clip with thumb pressure.

Thanks, fore warned is forearmed.
